A warm-up should gradually prepare the body for exercise by raising heart rate, increasing blood flow to the muscles, and improving joint mobility. The idea is to ease into activity so muscles, nerves, and the cardiovascular system are ready for what comes next. Start with a few minutes of light cardio to gently elevate temperature and circulation, then include dynamic movements that mimic the upcoming workout to improve range of motion and neuromuscular readiness. Static stretches held for long periods are best saved for after the workout, because they can temporarily reduce power and performance if done before activity.

Resting completely for several minutes won’t achieve these goals, since rest keeps the body in a low-activity state and leaves muscles cool, making the upcoming workout less efficient and potentially increasing injury risk.
